pm4py.visualization.dfg.util.dfg_gviz.get_activities_color(activities_count)[source]#

Get frequency color for attributes

Parameters:

activities_count – Count of attributes in the log

Returns:

Color assigned to attributes in the graph

Return type:

activities_color

pm4py.visualization.dfg.util.dfg_gviz.get_activities_color_serv_time(serv_time)[source]#

Gets the color for the activities based on the service time

Parameters:

serv_time – Service time

Returns:

Dictionary associating each activity to a color based on the service time

Return type:

act_color

pm4py.visualization.dfg.util.dfg_gviz.get_min_max_value(dfg)[source]#

Gets min and max value assigned to edges in DFG graph

Parameters:

dfg – Directly follows graph

Returns:

  • min_value – Minimum value in directly follows graph

  • max_value – Maximum value in directly follows graph

pm4py.visualization.dfg.util.dfg_gviz.assign_penwidth_edges(dfg)[source]#

Assign penwidth to edges in directly-follows graph

Parameters:

dfg – Direcly follows graph

Returns:

Graph penwidth that edges should have in the direcly follows graph

Return type:

penwidth

pm4py.visualization.dfg.util.dfg_gviz.sort_dfg_reachability(dfg: List[Tuple[str, str]], start_activities_to_include: List[str], end_activities_to_include: List[str]) → Tuple[List[str], List[Tuple[str, str]]][source]#

Sort the edges of the directly-follows graph based on reachability principles (start activities are putting at the beginning, end activities at the end)

Parameters:

  • dfg – List of edges of the directly-follows graph (without frequency/performance annotation)

  • start_activities_to_include – Start activities

  • end_activities – End activities

Returns:

  • sorted_activities – Activities sorted by reachability

  • sorted_edges – Edges sorted by reachability

pm4py.visualization.dfg.util.dfg_gviz.graphviz_visualization(activities_count, dfg, image_format='png', measure='frequency', max_no_of_edges_in_diagram=100000, start_activities=None, end_activities=None, serv_time=None, font_size='12', bgcolor='white', rankdir='LR', enable_graph_title: bool = False, graph_title: str = 'Directly-Follows Graph')[source]#

Do GraphViz visualization of a DFG graph

Parameters:

  • activities_count – Count of attributes in the log (may include attributes that are not in the DFG graph)

  • dfg – DFG graph

  • image_format – GraphViz should be represented in this format

  • measure – Describes which measure is assigned to edges in direcly follows graph (frequency/performance)

  • max_no_of_edges_in_diagram – Maximum number of edges in the diagram allowed for visualization

  • start_activities – Start activities of the log

  • end_activities – End activities of the log

  • serv_time – For each activity, the service time in the log

  • font_size – Size of the text on the activities/edges

  • bgcolor – Background color of the visualization (i.e., ‘transparent’, ‘white’, …)

  • rankdir – Direction of the graph (“LR” for left-to-right; “TB” for top-to-bottom)

  • enable_graph_title – Enables the visualization of a graph’s title

  • graph_title – Graph title to display (if enable_graph_title)

Returns:

Digraph object

Return type:
